Qemu Manager is an interface for QEMU that makes it easy to understand and use for average users. It provides facilities for configuring, running and managing virtual machines and the associated storage, peripherals and devices.

QEMU is a processor emulator that allows VMWare-style virtual machines, enabling users to run another operating system inside, including Windows and Linux. Using a technique called "dynamic translation" QEMU can virtualize different system architectures including PowerPC, S390, and more.

Open qemumanager.exe.manifest with a text editor and delete the tag <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2"> along with its content (this way Qemu Manager doesn't request elevation when launched under Windows Vista/7)

Administrator rights are required for KQEMU Accelerator support, and if you don't want to leave any trace on the host machine, you must uninstall the driver upon exit.

MobaLiveCD front ending for QEMU offers a wonderfully simply one click VM particularly for the inexperienced user such as myself. Unfortunately my experience parallels that of einstein on the MobaLiveCD page. In trying to run Puppy 5 boot time was about 10 minutes and response to key clicks was on the order of 30 seconds. I also set up a VM using QEMU and tried to run Puppy. The results were the same.(This was my first attempt at setting up a VM so I could have done it wrong).

However, the blog on MobaLiveCD on this website suggests much better results are possible. It also offered a possible clue to the slowness. In the blog ashghost points out that MobaLiveCD is only for 32 bit systems. My system is an XP Pro 64 service pack 2 running on an AMD 64 x2 Dual Core 5200+.

I have entered this comment on both the MobaLiveCD and QEMU pages because it is applicable to both.

Could someone help me.I've just downloaded the portable 7.0 version, and used on a usb stick under win7. After tried to use on another pc with Win XP and letter drive changed the Manager pop up some error message box that cannot resolve the drive letter and path that was assigned to the image in the win7 pc.Now the path is {QM}\images isnt it?So only the letter is another... why qemu search the that path.What could i do to resolve this problem i need a version that could run on every system and in a stick not installed or i am force to use the installation version.

Someone please consider making a cleanup utility to automatically clean up after Qemu!!!That would be an excellent thing and would make using it easier for the less technically minded portable enthusiast.

CrazyJohnny, if you mean VMWare Server does not support USB Devices then you are incorrect, VMWare Server supports USB devices and version 2.0 supports USB 2.0 (thank goodness!) the only thing to note is that with at least version 2.0 the Image host is the only system it can pull USB ports from, unlike CDs where it can use the server or host or virtual.

Can anybody tell me how to create a VM (virtual machine) of XP with Qemu?

filobus2008-09-03 08:21

for alberto: Mojopac needs administrator privilegies (you can use usher, but even that needs admin privileges)...

alberto2008-08-08 08:48

I am just starting with virtual machines. But if you want to take your desktop abroad in a USB portable way, you could try the free version of Mojopack (3rings). It does that in an authomatic way. Although that shouldn't be considered an easy task... You should read the forums for a while.To do secure connections, you should only trust https:// connections. Besides spyware and keyloggers, there is also the problem of proxy servers that could read you data if it is not encrypted like when using SSL.Sandboxie also takes care of not leaving trace of your browsing and not catching viruses.

I installed a small version of winxp in the qemu manager.I am able to run it in a Winxp computer without administrator rights.

Do you know a way of transfering files from inside the virtual machine to the physical usb drive without installing any software in the real computer ?

CrazyJohnny, I'm traveling a lot, and I find myself in many Internet-cafe places all over the world. I'm never feel comfortable to login to my personal accounts from those computers.So, If there is an option to run a small version of win-xp from a thumb-drive on any computer, it could be great !!That way, I can login to my personal accounts, and for my bank account from any public computer - without any fears.I tried to minimize win-xp with nLite, but I don't know what is the minimal configuration of win-xp that requires to run Firefox on win-xp inside Qemu-Manager.I found an article about how to minimize win-xp for Asus Eee pc (http://www.i64x.com/eeexp.php, that minimized version don't work for Qemu-Manager.Can you help with that information?(Thanks for your time)

CrazyJohnny2008-04-17 09:28

@John, I run a VM (virtual machine) of XP on a non admin PC (using the installed OS). Running an OS from a USB (bypassing system OS) can be done, but there are some big IFs (like USB boot support from the motherboard). Plus most IT dept won't allow non registered PCs to access the network.

What benefit are you looking for by surfing from your version of XP? It likely would not bypass any IT controls.

a, you have acceleration enabled? I honestly can't tell much difference between VMware and Qemu. Except on PCs that I've had VMware on systems lag for about 30 seconds after logon while VMware driver starts (annoying as hell).

Qemu Manager keeps improving! Much better interface. But the speed is a still a disapointment, compared (to the times I had vmware installed) it seems like the disks loaded just like if the os was installed for vmware, it's really slugish for qemu(note I don't have the kqemu driver, because I've had problems where qemu would freeze turn into a lingering process and won't close no matter what, despite that VMWare is not portable at all, and it's a freaking huge download compared to Qemu Manager so it's an even bigger disappointment because of that!

John2008-04-05 04:41

To 'CrazyJohnny':Can you please post a link to how-to run xp on a non-Admin PC (using QemuManager), and browse the web with that OS ?It looks amazing, but I have no idea how to perform that.(meaning, running that OS from a USB thumb-drive)

CrazyJohnny2008-03-26 14:01

Everything works great! I'm running a micro-ized XP very quickly on a non-Admin PC; freakin amazing!

Very impressiv tool, but has one little lack. When using not the default keyboard, then the specified keboard is written to the commandline Parameters and this ends to a wrong keyboard. Like written on the QEMU Website it is only necessary to set the keyboard in the command line, when using the vnc parameter. In the earlier version 4.0 this could not happen, maybe the developer of this greate tool can fix this behaviour.
